The MAX5590–MAX5595 octal, 12/10/8-bit, voltage-output
digital-to-analog converters (DACs) offer buffered
outputs and a 3μs maximum settling time at the 12-bit
level. The DACs operate from a +2.7V to +5.25V analog
supply and a separate +1.8V to +5.25V digital supply.
The 20MHz 3-wire serial interface is compatible with
SPI?, QSPI?, MICROWIRE?, and digital signal
processor (DSP) protocol applications. Multiple devices
can share a common serial interface in direct-access or
daisy-chained configuration. The MAX5590–MAX5595
provide two multifunction, user-programmable, digital
I/O ports. The externally selectable power-up states of
the DAC outputs are either zero scale, midscale, or full
scale. Software-selectable FAST and SLOW settling
modes decrease settling time in FAST mode, or reduce
supply current in SLOW mode.
